Gen 8 has already been confirmed, which supports the idea that this isn't the end, but rather just a turning point. Every generation as had new game mechanics and old ones taken out, such as in gen 2 when the critical hits system was simplified. There are many other explanations for what happened in gen 7 and Sun/Moon, such as fan pressure for changes and the need for a "recap". Of course, I too hope that Pokemon continues for a long time to come.
